Investigation regarding the physiological effects of cobalt on physiological functions in Drosophila, crayfish, and crab: Behavioral, cardiac, neural, and synaptic properties.

Cobalt, a metallic element found naturally in the earth's crust, is essential to survival. It is the active center of cobalamins such as vitamin B12 and is also a micronutrient for bacteria, algae, and fungi. The effects of cobalt (II) chloride (CoCl), the inorganic form of cobalt, are dependent on the dosage.

Acute lipopolysaccharide (LPS)-induced cell membrane hyperpolarization is independent of voltage gated and calcium activated potassium channels.

The gram-negative toxin lipopolysaccharides (LPS) are known to trigger inflammatory cytokines in mammals, which can result in pathological responses. Upon treatment of bacterial sepsis with antibiotics, the lysing bacteria can present a surge in LPS, inducing a cytokine storm. However, LPS can also have direct cellular effects, including transient rapid hyperpolarizing of the membrane potential, blocking glutamate receptors and even promoting release of glutamate.

Examining evidence of lung cancer stigma among health-care trainees.

Background: Innovations in lung cancer control and care have started to transform the landscape of lung cancer outcomes, but lung cancer stigma and biases have been implicated as a deterrent to realizing the promise of these innovations. Research has documented lung cancer stigma among the general public and lung cancer survivors (self-blame), as well as clinicians across many disciplines. However, studies have not explored lung cancer stigma in health-care trainees.

Pharmacological profiling of stretch activated channels in proprioceptive neurons.

Proprioception in mammals and invertebrates occurs through stretch activated ion channels (SACs) localized in sensory endings. In mammals, the primary organs for proprioception are the intrafusal muscle spindles embedded within extrafusal muscle. In invertebrates there are varied types of sensory organs, from chordotonal organs spanning joints to muscle receptor organs (MRO) which are analogous to the mammalian muscle spindles that monitor stretch of muscle fibers.
